I suppose you do need something when you store it to
a GSList.  What is the point of storing pointers to freed
memory to a GSList?

You have to free it yourself before freeing the list or
individual elements.

GSList can store some untyped pointers.  It has no idea of
what they point to (or if they are real pointers at all),
therefore it cannot make copies of the data, cannot free
them, etc.  It just stores some untyped pointers.
